摘要: A weatherseal or belt-line seal for a vehicle is formed by extrusion of an olefin-based thermoplastic elastomer or vulcanizate (first TPV) as an elongate body of arbitrary length and cross-section. The cross-section is adapted for use in a particular location in the opening of a structure to be protected against wind and rain, for example around the glass of a window in a vehicle's door, or around the opening (at the periphery) in which the door is closed, so as to present at least one sealing surface against which the glass or door may be abutted to provide a seal against the elements. A slip-coating is co-extruded onto one or more longitudinal sealing surfaces of the body; the slip-coating contains a novel compatibilizer which allows thermoplastic polyurethane (TPU) to be chemically bonded to a graft copolymer of polypropylene (PP) and a compound having two anhydride groups. The reaction product of the grafted PP and the TPU effects a thermal bond with the sealing surface of the body. The slip-coating has a combination of softness and abrasion resistance which are uniquely suited for the purpose of the weatherseal.

摘要翻译: 用于车辆的耐候密封带或带状线密封件是通过挤出作为任意长度和横截面的细长体的烯烃类热塑性弹性体或硫化橡胶(第一TPV)形成的。 横截面适用于要防止风雨的结构的开口中的特定位置,例如在车辆门的窗户玻璃周围或围绕开口(在周边)处,其中 门关闭,以便呈现至少一个密封表面,玻璃或门可抵靠该密封表面以抵靠元件提供密封。 滑动涂层共挤出到主体的一个或多个纵向密封表面上; 滑移涂层含有一种新颖的相容剂,其允许热塑性聚氨酯(TPU)与聚丙烯(PP)和具有两个酸酐基团的化合物的接枝共聚物化学键合。 接枝PP和TPU的反应产物与本体的密封面发生热粘合。 滑爽涂层具有柔软性和耐磨性的组合,其特别适用于耐候密封胶的目的。
